I'm new to this forum, and I'm looking for some input. I'm trying to "dial" in a limewash recipe. The problem that has arisen is chalking. Not, as in completely coming off the wall, but very subtle. I'm trying to keep the recipe simple,economical, & "green" as possible.
So I've allowed 5 lbs. hydrated type "S" lime stand in 1gal. h2o for a day. Then mixed hydrated type "S" lime powder with 1.5 lbs. dissolved salt & 2 qts. h2o. Been actuallly overall pleased with results.
However, the chalking is a concern. As I'm an interior natural clay plasterer, and want to keep chalking to a minimal. The product I use, is compatiable with limewashing. Only thing I've heard is possibly adding potash alum to mix. Any other suggestions would greatly be appreciated. Thanks everybody. Ck

if you are after natural (homemade) you need to add casein and vinegar, work out your own proportion.

you can add that to the mix (limewash or make as a sealer)
